hey texas!! yes the malachite does do that even with the most delicate care one takes, overtime it's inevitable that the color does change. did you go to the Bower museum to see princess grace's jewelry? I was there when they had the exhibit and saw her malachite piece, boy was it dark. The striations weren't that visible and from a distant it almost looked black. Of course I can't say whether she took good care of the piece (that could random from person to person) but as far as i'm concerned and talking to several jeweler friends of mine, the potential is high. plus, it cannot touch water or the shine will be stripped off and darken. I hope you take extra care of your malachite so it stays new and beautiful forever!! I saw the wood in the store, but never took a close look or tried it on. Hubby and I just couldn't justify spending money on wood jewelry.
I am referring to the photos of her pieces that are in one of my large VCA coffee table books ( gift from SA)....
My pieces are a. 20 motif, LE ten motif and earrings. Not much worry about encountering water, thank goodness. I'm really surprised that they offer malachite in a ring. That would be too risky for me. Re the wood.... my DH feels the same way that you do!! ("Wood?!") I still bought it when the LE pieces came out because I love the history behind the LE wood source. Years ago VCA made other pieces with this wood. There is a special history. It's very hard and polished. Feels more like rock than wood.
